Fasten in p.97, review your notes, answer the questions, and start quizzing each other!!!
When you've mastered one of the Big Picture questions, have someone sign off that you're an expert.
Videos on transport (passive and active) - and another about active transport - and another about faciliated transport, there's a bunch online!

96 BIg Picture part 2 - Energy in Organisms
We're looking at the big picture of energy, and how cells use it for metabolism to make the changes (reactions) necessary to stay alive... Make sure you can explain:
It's ridiculous how there are so many videos and sites about this; let us know if you find one that's really helpful!
For you above and beyonders...
Here's a really detailed video about cellular respiration - hang onto it for AP BIOLOGY
Bonus question - do you think chloroplasts and mitochondria have enzymes that make these reactions happen faster?
- the role of ATP,
- how cellular respiration and photosynthesis are related,
- and where do chloroplasts and mitochondria fit into the picture.
- the roles of Glucose, Oxygen, Carbon Dioxide, Water, and sunlight.

95 Big Picture Concepts, part 1
Fasten in the handout, grab your seat belts, and let's bring it all together.
How are organisms organized?
- Look at this and this and this and ...
What's so special about carbon? (Why are we carbon based life-forms?)
- Robert Krulwich from NPR has a little video series
What are the most common elements in life? (CHON + PS)
What's so important about Enzymes? - they just control the world of chemistry (and life)!
- Looking at the energy of reactions, and how enzymes make things easier...
- How enzymes affect chemical reactions (5:26 is the best part about energy)
- A good video overview of enzymes - lots of details, and here's another video
Proteins - what are they made of?
- many enzymes are proteins, which are made of amino acids (what do ribosomes do?)
- DNA and the nucleus control which proteins are being made at any time, and since enzymes affect chemical reactions, the nucleus can determine which reactions should occur in the cell by making different ENZYMES (among other ways too...)

94 Cancer, a closer look
Today's learning goals are:
1. Learn about the relationship between cancer and cell division (mitosis)
2. Visually recognize the stages of cell division (PMAT vs I)
3. Really master the characteristics of the stages of cell division (PMAT)
Keep these in mind as we explore the difference in cancer cells and normal tissue!
Fasten the handout to page 94 in your notebook
Complete the questions above the data table
Go to the virtual lab here
follow the instructions for the virtual lab and record your data in the data table.
Answer the question at the bottom of the data table.
Need help calculating percents? Do it like this:
Cells in mitosis - first add up all the cells in p or m or a or t = P+M+A+T
Let's say that there is 1 cell out of 20 in mitosis. 1/20 * 100% = 5%
Now there should be 19 in interphase, so 19/20 * 100% = 95%
does 5% + 95% = 100% --> yes, so we're probably doing it correctly :-)
When done, work on something else in your notebook, or go above and beyond by researching something that interests you about cancer.

The Egg part 4
A. Complete the day 4 activities, data, and recording for the Egg.
B. Dispose of the egg in the ziploc bag
C. The 2 graphs are homework
Keep working on Project 76 - scroll down to the blog entry for details
We all noticed that the eggs were a bit bigger after sitting in the water, some even burst. Hmmmm... we also had a nice little popping ceremony in ziploc bags, and "buried" our eggs in the special place...
Question to consider - why did the egg get bigger, then smaller, then bigger? What do you think is moving in/out of the egg?

The Egg part 3
Start with the usual:
A. Get a computer for your table (leave your ID, please remember to plug it in when you return it!)
B. Log in
C. Go to the blog
D. Turn your notebook to the correct page
E. Complete the tasks
THE EGG, part 3
1. Follow the instructions in the packet for day 3.
2. Record your observations in the data table - leave this out for discussion
3. Make sure to dispose of the syrup in the proper containers (NOT THE SINK!!!)

The Egg part 2
A. Write down this blog address in your table of contents "CHAPMANBIO.BLOGSPOT.COM"
B. Get a computer for your group and log in
C. Go to the class blog!
1. Observe your egg and record your observations (use the data table)
2. Measure how much vinegar is left, and dispose of it properly
3. Rinse and weigh your egg (don't let the egg touch the balance - figure it out!)
4. Now figure out how you are going to do the DAY 2 part of the EGG lab
5. When it's your group's turn, do the DAY 2 stuff for your egg investigation
6. Make sure to record ALL of your MEASUREMENTS, show any CALCULATIONS, and write down your observations...
A few things we noticed... soaking the eggs in 100ml of vinegar for two days didn't quite dissolve the entire shell so we had to wash it a bit. Replacing the vinegar after one day helped, or using a 400ml beaker and 200ml of vinegar worked pretty well :-)

76 Cell Organelles part 1
1. Use the handout to create a foldable for the first 8 Cell Organelles
2. Pictures are on the outside, inside has what it is, and what it does.
3. Use Cell Organelles to help you finish the foldable
4. Check out the video links (see below or use the LINK tab at the top of this page). If you're getting blocked on campus, look in my OUT folder (ALL PERIODS) for the videos, or just wait until you have internet access off campus.
